title: [Analysis of coronary rotational atherectomy related complications].
abstract: OBJECTIVE
  To analysis the complications of coronary rotational atherectomy and evaluate the safety of this procedure.
  
  
  METHODS
  A total of 250 rotational atherectomy cases from April 1994 to February 2012 were screened retrospectively and 22 cases patients (8.8%) with rotational atherectomy-related complications were included in this analysis.
  
  
  RESULTS
  Among these 22 patients, all lesions were either type B2 or C calcified lesions as evidenced by coronary angiography. After the rotation procedure, there were seven cases (2.8%) with slow reflow and two (0.8%) cases with no reflow. Seven cases (2.8%) developed severe coronary spasm and two cases (0.8%) had sinus bradycardia. Coronary dissection occurred in two cases (0.8%), while one case (0.4%) had coronary perforation and cardiac tamponade. Burr entrapment happened in one case (0.4%). There was no malignant arrhythmia, acute myocardial infarction, emergent coronary artery bypass graft or device related death during and post procedure. Comparison with baseline data, the concentration of CK-MB elevated significantly after the rotational atherectomy [(31.2 ± 4.8) mmol/L vs. (11.4 ± 6.5) mmol/L, P < 0.05].
  
  
  CONCLUSIONS
  Coronary rotational atherectomy is safe and procedure-related complications are rare.
